BTES prepared me for the Plumbing trades knowledge and Business and Finance exams. BTES shows you the process for navigating text books to find what you are looking for quickly, highlighting and tabbing the right places, and providing you with useful information and practice tests in their study guides. These practices allowed me to pass both the trade knowledge and business/finance the first time. Trust me, you don’t want to take either of these tests twice. Follow the process, you will be successful.
